I'm not on ADT myself, but this is a question I received from a friend of mine, and i hope somebody here can help, as I have no idea... Perhaps a lisp routine might do it...?
What can he do?"I got a Autocad question for you;
Some clown in the office decided that it would be a good idea to bind an xref, explode it and make this drawing part of our actual working drawings;
Any idea how I can get rid of the preamble e.g. 1st$0$... from all layers, blocks, linetypes etc without renaming them individually?
Guess what, this has been done to 8 floors of drawings, elevations etc."
Any help would be appreciated.
